Hydraulic Model Test of Head Pivot in Zangao Hydropower Station
In order to verify the rationality of the design of flow capacity,flow pattern,downstream erosion and anti-icing under different working conditions such as full opening and partial opening of flood discharge sluice,overflow of spillway dam without sluice in Zangao Hydropower Station,a hydraulic model test with a geometric scale of 1∶50 is carried out on the head pivot of Zangao Hydropower Station,and the test results were analyzed.The results show that the discharge capacity meets the design requirements;The strong suction vortex is easy to appear near the inlet of the left side hole of the flood discharge sluice,and the scouring at the outlet of the stilling basin is more serious;Raising the reservoir water level to 1611.42 m can effectively prevent ice.The model test can provide basis for the engineering optimization design of the next stage.
